i To all whom z't may concern.-

Be it known that I, FRANK P. LEONARD, a citizen. of the United States, residing at Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Roofings, of which the following is a specification.

This invention relates to improvements in roofing.

'lhe primary object of `this invention is the provision of a novel type of roofing section, which maycooperate with adjacent vsections of like nature in providing a waterproof roof, the connections of adjacent sections of which are of the most durable and i water roof arrangement.

A urther object of thisV invention is the provision of a roofing section, which may be used in so, far as structural features off the same are concerned, for shingle or roll roofing, embodying certain novel receiving and inserting flaps.

A further object of this invention is the provision of roofing material of the above described character, which may be manufactured so that workmen may readily lay the same,'. without the necessity of providing liners and markers; the interitting connections of adjacent novel sections, being such thereon.

as to make-the laying of the roofing practically self Other ob'ects and advantages of this invention will be a parent during the course of the following etailed description.

In the aocompanyin a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views.

Figure 1 is a fragmentar perspective view of a roof structure, showing the improved roong material, as cooperatively used drawings, forming tion, as the same is manufactured and the condition in which the saine is delivered for a roofingoperation.

Figure 6 is a' fragmentary perspective view of cooperating parts of a roofing section. f

In the drawings, wherein for the purpose of.illustration is shown but. the preferred embodiment of this invention, the letter A generally designates a section of the iin.

proved roofing material, which may be either of the roll or shingle type. This roofing may be of sheet paper, fabric, fiber, or analogous flexible base material, including a body portionvlO, which-may be rectangular in formation, and the 'top Surface of which may be provided with any of the well known type of protecting coating, suoli :is

gravel, slate, or the like, /aflixed as by tar' ring to the upper surface of said body portion. The body portion 10. of the roofing section A preferably hasmarginal flaps at all edges thereof. This fiapv arrangement may consist of an upper 4receiving flap 15; lower inserting flap 16, .oppositely positionecl on a marginal edge with respect tol the receiving flap 15; an end receiving flap 17; -and an end inserting iap 18. a

In case the novel roofing section A is used as roll roofing, the receiving flap A15 will be disposed at the upper, longitudinal edge of the roll, while the inserting Hap 16 is dis-` posed at the lower longitudinal edge of the roll. The receiving end Hap 17 is at the end of the'roll, while the inserting tlap 13 is. at the starting end of the roll.

The receiving kflaps 15 and 17 are of analogous-construction, and are overturned upon the body portion 10, during'manufacture of the section A. The facing'surfaces of each of the receiving flaps 15 and 17 with the body portion 10 are provided with :id--

hesive coatings 20, so that the socket provided by the receiving flaps and the bodv lportion 10 are interiorly provided with :id-i

esive material. 4To prevent the adhering of the facing coatings 20 of adhesive material, it is preferred that a temporary protecting strip 25 be rovided foi-'insertion in the sockets provided by the receiving -flap which maintain the Y, facing adhesive sur aces ofthe flaps and body portion in separated relation. These separating strips 25 may be wax paper, or may be any anal-` ogous temporary protecting means, such as -nal edge and at the starting end of the body portion 10, are fabricated as to lie in the plane with the body portion 10, being contiguous therewith, and preferably hav.

ing marking lines 28, upon which the same may be bent in underfolded relation uponV thev bottom of the body portion 10, for insertion into the sockets of the receivingllaps 15 and 17 of adjacent sections. The gravel coating 11 also terminates short of the in* serting flaps 16 and 18.

None of the receiving or inserting flaps of the improved section A extend for the full length of the marginal edge of the body portion upon which they are positioned, but are arranged, as to their length, to most readily .conform to the interfittmg connection of the. sections to provide an' impervious roofing, which may be readily7 attached to a roof. Thus, the receiving flap 17 and the insertingap 18, which are positioned at the ends of the roofing 'section A, are preferably of the same length, having their top edges 30 terminating inwardly of the'free marginal edge 26` of the rece1v1ng flap 15. These edges 30 of the flaps 17 and 18 may be in'alignment with the free edge 26 of the receiving flap 15, but may not be disposed beyond alignment of the edge 26 inte the inserting flange extended. The lower end edges 32 of the receiving and inserting flaps 17 and 18 respectively, may terminate in alignment with the folding line 28 of the lower longitudinal inserting flap 16 of the section A, substantially as is illustrated in Figure 3 -of the drawings. The upper or longitudinal receiving ilap 15 has one end edge 33 thereof preferably in alignment with the folding line 28 of the end insert-ing flap 18'. The opposite end edge 34 of the top receiving flap 15, preferably terminates in alignment or inwardly of the free marginal edge 26 of the end receiving flap 17, so that the receiving flap 15 doesl not extend into the line of the receiving flap 17 The body portion 10 of the improved section A provides an exposed corner 35 at the end edges 34 and 30 of the receiving flaps 15 and 17.

The lower inserting -ilap 16 preferably extends-hem adjacent the folding line 38 of the receiving flap 17 to an opposite end edge 39, which is positioned in spaced relation with the fold line 28 of the inserting flap 18 for a distance substantially equivalent to the width. of the inserting flap 18, andA substantially as is illustrated in Figure l3 of the drawings. The vcorner of the body portion 10 adjacent the end edges 30 and 33 of the flaps 18 and 15 respectively is cut away or removed. '.Referring to the laying ofthe roofing 'sections A, the operations are aptly illustrated in Figures 1, 2, and 4l of the drawings. Assuming that the sections A are in the form of roll roofing, the roll is extended along the roof, and a lower section A is attached to the roof B ladjacent the eave thereof. The attachment of this lower section A is first accomplished bynailing the longitudinal inserting flap' 16 to the roof B, as by the nails 40, and bending the section A- to overlie the reef B. The longitudinal inserting flap 16 of the next upper section A is then inserted int the socket of the upper inserting flap 15 of the lower attaching section A, and the body portion of the section` being attached. is disposed substantially in the position .illustrated by dotted lilies in Figure 1 of the drawings, while nail eli-ments 41 secure the inserting flange 16 of the sections being'attached in the receiving flap of the lowermost section A and to the roofing B. The body portion of the section being attached is then bent upon the roof B, and the laying of the sections A is continued throughout the roof. It will be noted that when the body portion of the sections are attached to the roof, all of the securing elements 40 and 41 will be hidden from view, and disposed in protected relation.

The temporary protecting paper ormaterial 25, is of course, removed from the adhesive surfacesof the receiving' flaps 17 and .15, so that when the inserting flap of an adjacent roof section is disposed within the socket of Vthe receiving flap, the insert# ing flap will be engaged by the adhesive surface 20 upon both sides. When the roof is of such length as to require the laying of a plurality of sections, the receiving and in= serting flanges 17 and 18 of the adjacent sections interconnect. The position and relationof the flaps of adjacent sections, is

-well illustrated in Figure 4, where the adjacent sections at the ends thereof are disposed for an assembling operation. It is easily understood from this view, that when the rolls or the adjacent sections are Aconnected in extending relation, the longitudinal receivingvand inserting flanges will be in unbroken alignment, to properly cooperate with the next lower and upper rows of sections A.

The receiving flaps 15 and 17 are folded, while the paper is in process of manufacture, and whilethe same is pliable and hot, so that the same will not break, and will assume a` permanent overlapping relation upon the body of the section. This is a convenient arrangement, not only from the standpoint of assemblage of the sections in self aligning relation,s but because or' the saving of time, labor, and expense in attaching the roofing, as it is readily understood that the output ofthe sections A on aproduction basis, will permit of 4their manufacture `for a great deal less lsuin in their finished form thanV would be possible for a roofer to shape the same during a roof laying operation.

From the foregoing description of this ini vention, it is obvious that a roofing section has been provided, which may be attached, either in the shape of roll rooting or shingles, as to \provide an economical and weather proof roof structure. Laying operations have been reduced to alinin-imum inthe formation ofthe section as above described, as it is not necessary to apply any finishing coating or cenienting material during such laying operation, and in addition dispenses' with other oidinary laying opera- ,tions as it apparenti and has beenhereinbefore mentioned.

Various changes in the shape, size, and arrangement of parts may be made tothe -form of invention hereinshown and d'escribed, Without departing from the spirit of the invention or the scope of the claims.
